A chemical company makes two brands of antifreeze. The first brand is 40% pure antifreeze, and the second brand is 60% pure antifreeze. In order to obtain 180 gallons of a mixture that contains 55% pure antifreeze, how many gallons of each brand of antifreeze must be used?
First brand =
Second Brand=
Answer:
Step-by-step explanation:
Let x be the portion of 60%
180 - x is the portion of 40%
0.60x + 0.40(180 - x) = 0.55(180)
0.60x + 72 - 0.40x = 99
0.20x = 27
x = 135
180 - 135 = 45
First brand = 45 gallons of 40%
Second Brand = 135 gallons of 60%

Answer:
a) k = 2/5
b) y = 2/5x
c) y = 2 3/5
Step-by-step explanation:
a)The proportional relation is described by the equation ...
y = kx . . . . . . k is the constant of proportionality
The value of k can be found by dividing the equation by x:
y/x = k = (2 1/4)/(5 5/8) = (9/4)/(45/8) = 18/45
k = 2/5
__
b)As above, the equation is ...
y = kx
y = 2/5x
__
c)Using 6.5 for x, we have ...
y = (2/5)(6.5) = 2.6 = 2 3/5
In the figure shown, line AB is parallel to line CD.
Part A: What is the measure of angle x? Show your work. (5 points)
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
Answer:
x = 53
Step-by-step explanation:
AB ║ CD Given
m ∠APQ = m ∠RQP = 62° If parallel lines, then alternate interior angle =
m ∠DRP + m ∠PRQ = 180° These angles form a linear pair which = 180°
115° + m ∠PRQ = 180° Substitution
m ∠PRQ = 65° Subtraction
m Δ QPR = 180° Definition of triangle
m Δ QPR = m ∠PQR + m ∠QPR + m ∠PRQ the sum of the angles of triangle
180° = 62° + x + 65°
180 = 127 + x
53 = x
A water sprinkler covers the area shown in the figure.
It moves through the covered area at a rate of about 5 per second.
What is the measure of the are covered by the sprinkler?
If the sprinkler starts at the far left position,
how long will it take for the sprinkler to reach
the far right position?
A water sprinkler has a rotational motion in order to reach a broad area
from its stationary location.
The time it takes the sprinkler to reach the far right position is 36 seconds.
Reasons:
The given parameter are;
The angular speed of the water sprinkler, ω = 5° per second
Location where the sprinkler starts = The far left position
Required:
The time it takes the sprinkler to reach the far right position.
Solution;
The angle covered by moving from the far left to the far right, θ = 180°
Time required is given as follows;
[tex]\omega = \mathbf{\dfrac{\theta}{t}}[/tex]
Therefore;
[tex]t = \dfrac{\theta}{\omega}[/tex]
Which gives;
[tex]t = \dfrac{180 ^{\circ}}{5^{\circ}/s} = 36 \, s[/tex]
The time it takes the sprinkler to reach the far right position, t = 36 seconds.

#14 A scale drawing of a rectangular room measures 2 cm by 4 and 1/4 cm. E
The scale used for the scale drawing is 1/2 cm = 5 ft. Carpeting will cost
$8.50 a square foot. How much will it cost to buy enough carpet to cover
the floor of this rectangular room? (**numbers and decimal only in answer
** NO $$ NO comma**) *
Answer:
Step-by-step explanation:
Width
1/2 cm = 5 feet
2cm = x Cross Multiply
1/2 x = 2 * 5 Combine
1/2 x = 10 Multiply both sides by 2
x = 20
Length
1/2 cm = 5 feet
4 1/4 cm = x Cross Multiply
1/2 x = 4 1/4 * 5 Combine the right
1/2 x = 21.25 Multiply both sides by 2
x = 42.5
Room Area
Area = 20 * 42.5
Area = 850 square feet
Cost
1 square foot costs 8.5 dollars.
850 square feet costs 8.5 * 850
850 square feet costs 7225 dollars.

Myra incorrectly factors 15 a-20ab as 5a( 3-4ab).
Factor the expression correctly.
15a - 20ab
Here, '5' & 'a' are the common factors. So factor them out.
=》15a - 20ab
=》5a (3 - 4b)
Myra incorrectly put 'a' inside the bracket which is wrong because 'a' is a common factor too along with 5.

Answer:
The answer (using BEDMAS) is 27
Step-by-step explanation:
The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS
First solve the smaller bracket
18 + 2 = 20
So then it becomes 9 x [20 ÷ 5 - 1]
Do the division inside the bracket next
20 ÷ 5 = 4
Then it becomes 9 x [4 - 1]
Do then subtraction within the bracket
4 - 1 = 3
Then it becomes 9 x 3
Finally solve 9 x 3 which equals 27
If x > y, then will always be an integer.

The perimeter of a rectangle is 94 yards. The width is 23yards less than the length. Find the length and the
width of the rectangle.
Answer:
The length = 35 ; The width = 12
Step-by-step explanation:
Perimeter = 2L + 2W
Length = x
Width = x - 23
94 = 2(x) + 2(x - 23)
94 = 2x + 2x - 46
94 = 4x - 46
94 + 46 = 4x
140 = 4x
140/4 = x
35 = x The length = 35; The width = (35 - 23) = 12

Hannah has a chicken coop with six hens. Let X represent the total number of eggs the hens lay on a random day. The distribution for X is given in the table.
What is the probability that the hens lay a total of two eggs?
0.05
0.07
0.12
0.93
Answer:
0.07
Step-by-step explanation:
I'm sorry if its wrong
The probability that the hens lay a total of two eggs is 0.07. Therefore, the option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, Hannah has a chicken coop with six hens.
Let X represent the total number of eggs the hens lay on a random day.
Let the probability that the hens lay a total of two eggs be y
From the table,
X=0.02+0.03+y+0.12+0.30+0.28+0.18
We know that, the total of probability should be 1.
Now, 1=0.02+0.03+y+0.12+0.30+0.28+0.18
1=0.93+y
y=1-0.93
y=0.07
Therefore, the option B is the correct answer.

Members of the chess club held a bake sale to raise money. Cupcakes and cookies were sold. Cupcakes were sold for two dollars each. Cookies were sold for $0.50 each. The members sold a total of 450 items. Of the items sold 2/3 were cupcakes and the remaining items were cookies. How much did the chess club members raise for the cookies that were sold?
A=150.00
B=85.00
C=75.00
D=450.00
Total amount raised for the cookies is $75, Option C is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Cupcakes were sold for two dollars each.
Cookies were sold for $0.50 each.
The members sold a total of 450 items.
Let x be the number of cupcakes and y be number of cookies
x+y=450
Of the items sold 2/3 were cupcakes and the remaining items were cookies.
x = 2/3×450 = 300
Y= 450 - 300 = 150
The total amount raised from the cupcakes is $2× 300 = $600.
The total amount raised from the cookies is $0.50 × 150 = $75.
Hence, total amount raised for the cookies is $75, Option C is correct.
